Subject [jira] [Created] (REEF-1305) Make default group creation passive and moving the group creation before submitting tasks
Date Thu, 31 Mar 2016 19:04:25 GMT
Julia created REEF-1305:
---------------------------

             Summary: Make default group creation passive and moving the group creation before
submitting tasks
                 Key: REEF-1305
                 URL: https://issues.apache.org/jira/browse/REEF-1305
             Project: REEF
          Issue Type: Bug
            Reporter: Julia


Currently Default communication group is created in the constructor of GroupCommDriver. To
support fault tolerant, we will need to control the group creation/removing explicitly from
drivers. We can still keep the default group for client's convenience, but change its creation
to be passive instead of in the constructor. 
Besides, in most of Group Communication sample drivers and IMRU driver. the group is created
in the constructor of the driver. It should be moved to IActiveContext handler so that in
fault tolerant case, we can control the re-creation of the group.
